<u>Answer:</u> Electron has almost no mass.
<u>Explanation:</u>
Mass is defined as the actual matter that is contained in a substance. At an atomic level, it is expressed in atomic mass units.
The given options are the 3 subatomic particles.
Mass of the given subatomic particles are:
Proton = 1.007276u
Neutron = 1.008664u
Electron = 0.0005485u
Mass of neutron is slightly more than the mass of proton.
From the above information, it is visible that electron has a negligible mass.
Hence, the correct answer is electron.
Answer: The correct answer is "wind direction".
Explanation:
Coriolis effect: This is an apparent deflection of moving air or water caused by the rotation of the earth.
Currents are created by wind. Their directions are determined by Coriolis effect.
Currents are created by wind. The earth is in constant motion. It describes the rotation of the earth which steers winds and the surface current. The ocean surface currents are deflected by Coriolis effect.
The direction of the wind blows from north and south towards equator.
Therefore, the Coriolis effect influences wind direction.
Answer:
A) pH of the buffer is 3.44
B) pH of the buffer solution is 3.37
Explanation:
Relation between K_{a} and pK_{a} is as follows.
.
The relation between pH and pK_{a} is as follows.
![pH = pK_{a} + log\frac{[conjugate base]}{[acid]}](https://tex.z-dn.net/?f=pH%20%3D%20pK_%7Ba%7D%20%2B%20log%5Cfrac%7B%5Bconjugate%20base%5D%7D%7B%5Bacid%5D%7D)
pH of the buffer is 3.44.
b)
mol of HCl added = 11.6M *0.001 L = 0.0116 mol
In the given reaction, 
will react with 
to form
No. of moles of
And, no. of moles of 
= 0.12 mol
after the reaction :
No. of moles of = moles present initially - moles added
= (0.15 - 0.0116) mol
= 0.1384 mol
Moles of = moles present initially + moles added
= (0.12 + 0.0116)
= 0.1316 mol
As,
Since, volume is both in numerator and denominator, we can use mol instead of concentration.
![pH = pK_{a} + log \frac{[conjugate base]}{[acid]}](https://tex.z-dn.net/?f=pH%20%3D%20pK_%7Ba%7D%20%2B%20log%20%5Cfrac%7B%5Bconjugate%20base%5D%7D%7B%5Bacid%5D%7D)
= 3.347+ log {0.1384/0.1316}
= 3.369
≅ 3.37
pH after the addition of 1.00 mL of 11.6 M HCl to 1.00 L of the buffer solution is 3.37
